An explainer video is a short video that tells a specific audience what a product, service or idea is, why it matters to them and what to do next. Most are animated, most run between one and two minutes, and nearly all of them follow a structure that has been refined over years of landing pages, sales decks and onboarding flows.
That last part is worth stressing. An explainer is not a showreel or a mood piece. It has a job: to move a viewer from "what is this?" to "I get it, and I know what to do next" in the shortest honest time. Everything about format, length and style follows from that job.
What makes a video an explainer
Three things separate an explainer from other short brand videos:
- One audience. It speaks to a defined viewer with a defined problem, not to "everyone".
- One core message. It explains one thing well. Products with five features usually get one main explainer plus separate feature videos.
- A clear next step. It ends with a specific action: start a trial, book a demo, read the docs, call the clinic.
If a video does those three things, it is an explainer, whether it is animated, filmed or a mix.
The classic structure
Most effective explainers follow four movements. The proportions below are for a 60 to 90 second video, and they flex with the subject.
1. Problem (about 15 to 20 percent)
Open with the viewer's situation, not with your company. Show the frustration, cost or risk they already recognise. A good problem section makes the viewer nod within the first few seconds, which is what keeps them watching.
Keep it specific. "Managing invoices is hard" is weak. "Chasing three approvals by email before you can pay a supplier" is a scene the viewer can picture.
2. Solution (about 15 to 20 percent)
Introduce your product as the answer to that exact problem. Name it, state in one sentence what it does, and show the "after" picture. Resist the urge to list features here; the viewer only needs to know that a way out exists.
3. How it works (about 40 to 50 percent)
This is the body of the video. Walk through how the product delivers the result, usually in two to four steps. Show, do not tell: animated UI, a simplified diagram, a character moving through the new process. Each step should connect directly to a pain from the opening.
This is also where you can add a proof point if you have a real one, such as a well known integration, a certification or a concrete outcome you can stand behind.
4. Call to action (about 10 percent)
End with one action, stated plainly and repeated on screen. Two competing calls to action ("start a trial or book a call or follow us") weaken all of them. If the video lives on a page with a button, the CTA should match that button's wording.
Writing to this structure is covered step by step in our guide to writing an explainer video script.
Ideal length by channel
There is no single right length. The right length is the shortest one that still delivers the message, and that depends on where the video plays and how warm the audience is.
| Channel | Typical length | What the video needs to do |
|---|---|---|
| Paid social ads (feed, stories, short form) | 15 to 30 seconds | Hook in the first 2 to 3 seconds, work with sound off, one idea only |
| Organic social cutdowns | 15 to 60 seconds | One feature or one benefit per clip |
| Homepage or landing page | 60 to 90 seconds | Full problem, solution, how it works, CTA |
| Product page or feature launch | 45 to 90 seconds | Focus on one feature and its outcome |
| Sales outreach and decks | 60 to 120 seconds | Answer the questions buyers ask on first calls |
| Onboarding | 1 to 3 minutes, or a series of short clips | Get a new user to their first success |
| Help center tutorials | As long as the task needs | Task completion, often with chapters |
| Trade shows and events | 30 to 90 seconds, looped | Readable without sound from a distance |
Two practical notes. First, a long master video can be cut into shorter versions if you plan for it during scripting and storyboarding. Second, word count drives length more than anything else: at roughly 130 to 150 spoken words per minute, every sentence you cut saves real seconds.
Common explainer styles
The style should fit the audience and the subject, not just taste. A fuller map of options is in our guide to types of animation; here are the ones explainers use most.
Flat 2D and vector
Clean shapes, simplified characters and interfaces. The most common explainer style because it handles both people and products, stays on brand and is easy to update. Our 2D animation service is built around this kind of work.
Motion graphics
Type, icons, UI and data in motion, usually with no characters. Strong for software, fintech and B2B products where the message is about features, numbers or workflow.
Character animation
A recurring character (often a stand in for the customer) lives through the problem and the solution. Good for consumer products, healthcare, insurance and anywhere empathy matters.
Whiteboard and doodle
Hand drawn illustrations appearing as the narrator speaks. Works for education, training and complex processes.
Screencast plus animation
Real product footage, cleaned up and framed with animated callouts, zooms and transitions. Useful when buyers need to see the actual interface. The trade off is that it dates quickly when the UI changes.
3D
Used when the explainer is about a physical product or a mechanism, such as a device, a medical procedure or a machine.
Where to use an explainer video
Once you have one, put it to work in more than one place:
- Above the fold on the homepage or landing page, near the main call to action.
- In paid campaigns, as short cutdowns that lead back to the full version.
- In sales emails and proposals, so prospects arrive at the first call already understanding the basics.
- In onboarding emails and in app, at the moment a new user needs the explanation.
- At events and in showrooms, on loop with subtitles.
- In investor and partner conversations, where a clear one minute story saves ten slides.
- In support content, where a short video can answer a repeated question better than a long article.
How to measure an explainer video
Measure the video against the job it was made for. Views on their own say little.
Attention metrics
- Play rate. Share of page visitors who start the video. A low rate often points to placement, thumbnail or page layout rather than the video itself.
- Hook rate. In ads, the share of impressions that watch the first few seconds. This tests your opening.
- Retention curve. Where people drop off. A sharp drop in the first 10 seconds means the problem section is not landing. A drop just before the CTA means the middle is too long.
- Completion rate. How many reach the end. Compare across versions, not against an abstract benchmark.
Outcome metrics
- Conversion with and without the video. On landing pages, compare visitors who played the video against those who did not, or run an A/B test with and without it.
- Click through on the CTA, in the player or on the button below it.
- Sales cycle signals. Fewer "so what exactly does it do?" questions on first calls, shorter calls, better qualified demos.
- Support signals. Fewer tickets on the topic the video explains.
Set the measurement up before launch, so you have a baseline. If your analytics tool tracks video events, tag play, 25, 50, 75 and 100 percent progress, and the CTA click.
Before you commission one
A short checklist to have ready before talking to a studio:
- Who exactly is the viewer, and what do they already know?
- What is the single message they must take away?
- What one action should they take at the end?
- Where will the video live first, and which cutdowns do you need?
- What brand assets exist (logo files, colours, fonts, illustration style)?
- Who gives feedback, and who signs off?
- What is the budget range and the date you actually need it?
Clear answers here make the storyboard and animatic stages faster and the result sharper. For budgeting, our guide to explainer video cost walks through typical ranges and what moves them.
